According to his ruling, investigator Konstantin Kholmogorov was sentenced to 7 years in prison. He was punished for planting evidence against a sexual maniac in order to hold him accountable. On the day Kholmogorov was released, he crossed paths with the judge. At the same time, someone killed the same maniac. The police believe Kholmogorov is involved, but Kosarev thinks otherwise.
